APPARATUS FOR CUTTING AND FACING ARTICLES.

To (We r/101a- 1'7 may com-cm Be it known that I Rosro E. Como). of

Easthampton. in the count of I-lampshire and State'ot' Massachusetts, have invented certain new and useful Improvements in Apparatus for Cutting and Facing Articles. of which the following is a specification.

This invention relates to' a novel mode of cutting rings. disks, washers or other articles from a piece of stock and at thesame time truing or facing off one of the sides ofthe article thus cut and the objcct'is to enable the facing and cutting of the article to be performed in one operation whereby time may be economized in the manufacture of such articles. and to an apparatus for so cutting and facing the articles.

The invention has particular reference to the production of rings such as are used for paekings of steam engine pistons.- although it is capable of application to the production of other articles as well which require that the sideor face thereof opposite to, that Whereon it issevered from the body of the stock should be made true.

Briefly stated the invention consists in providing :a grooving tool adapted to enter the stock in one of its surfaces and to pro-' vide a side or facing tool .in such relation to the grooving tool that both tools may act simultaneously on the same piece of stock. and then giving the work and tools such relative motions of cutting travel and feed respectively that the grooving tool is caused .to advance progressively into the work to separate a piece therefrom and at the same time the side tool is aused to face otl' the outer surface of the piece being separated.-

-In the accompanyingdrawings is illustrated an apparatus for carrying this invention into effect.

Figure l is a plan view of such-an apparatus embodying the principles of the illvention. Fig. 2 is a'sideele 'ation of same.

Fig. 6 is a perspective view ofthe tools employed in carrying this invention into'ett'ect, showing the relation which they us ially occupy.

the foregoing figures, the letter :1 represents a side tool havmg a cutting edge 6 which is used for facing off that surface of ti wdrk.

vwhich extends in the plane or line of relative:

travel between the work and tool. @"represents the cutting ott' tool for acting on the side of the work. forming a groove thetqein, which finally passes completely through the work and sevcrs a piece therefrom. Both these tools are ,carried by a single holdet 'j consisting preferably of cooperating clamps J and c. a base plate or pedestal f on which the lower clamp c rests and a central post 9 passing through thebase and clamps. It

may benoted that the latter are preferably circular collars which are concentric with the axis of the post, although the form and proportions of thesame are not inaterial to this invention. The holder is supported upon the tool slide it of the 'lathe or on the corresponding tool carrier of any other form of machine tool and is preferably secured thereto by the bolt 71 having ahead j containcd. in an under-cut groove 7.; of the slide. The slank of the bolt is screwedinto the threaded interior of the post and serves to bind the holder against the slide. The. nut I screwed uponthe outer end of the post is employed for forcing the clamps (Z' and 6 against the tools and clamping the holders on the. slide h.

The tools (.1 and c pass between the clamps and r and are contained-in grooves or channels formed partially in each clamp. These grooves confine the toolswith a positive engagement. so that they annot slip out of place. The grooves-are inclined to one another so that the shanks and tools inserted therein converge .toward each other' at their cutting or operative. ends. By reason of this angularity between the tools the distance between their cutting ends may be readily adjusted and varied by moving thc tools as a whole endwise. When the tools are moved outward their cutting edges approach one another and when they are retracted their cutting parts separate. By these mains the tools may be adjusted to act"simultanconsly upon work of any desired thickness. The tool channels in the clamps are located so that suthclent stock is left in the clamps outside of the channels to give tlw'new-ssary amount ot strength and rigidity for holding the tools. This lltt'tssllzltts locating the grooves on opposite t: it

sidesof thefcenter'of the clamps and near enough to the center so that they intersect the 7 post g. The latter is accordingly slabbed ofi -or cutaway at m and n to form recesses. in alinement with the channels so that thestraigiht shanks of the tools may lie properly therein.v Preferably tools thus.

arranged relatively to one another 'are mounted upon'the cross-feed slide of a lathe to act upon 'a cylindrical piece of-stock,

somewhat in advance of the. cutting off tool so that it may finish" the facing. oft ofthe work before the end thereof issevered froml the-body of the, stock. The side tool also, serves as a gage, since when it is set in. po-; sition for operation the same setting .10- cates the grooving tool where it will cut oil? a piece of a predetermined thickness As both tools are mounted in the same. holder they are fed simultaneously and per-: form their two functions in one-operation; thus two operations are performed .at' one time on the same piece and the time factor of the'expense of manufacture is thereby diminished' I claim a clamping members provided with grooves;

or channels to contain cutting tools, and

tools havingtheir shanks contained insnchi grooves or channels, one of the tools having a cutting edge -on-its end and the other? having a longitudinaljcutting edge on the side adjacent to the first tool, and the" grooves being inclined to one. another and the t-o01s placed therein in such manner that they converge toward'the endshaving the cutting edges.
